Re: What is correct maai?
Maai is also a natural function of proper Hanmi (Stance). In our Aikido Hanmi/Maai is with the toes pointed in towards the Uke and no more than shoulder width apart. Irimi is always a half step with the toes/angle of "entry" of the lead foot toes pointed in. This allows you to strike/control your Uke and protect yourself from harm at the same instant.
Shoji Nishio Shihan stated that our Hanmi/Maai was one important technical distinction between our Aikido and the Hombu/Iwama Style.
